Abstract

Guía para conducción de películas, especialmente para visores de películas, proyectores, ampliadoras o semejantes con una ventanilla de imagen para la limitación del borde de la imagen y definición de la posición de la película, cuya amplitud de abertura, transversalmente a la dirección de transporte de la película, es menor que la anchura del camino del transporte de la película, caracterizada porque la ventanilla de imagen contiene dos partes de marco, que encierran entre sí el camino de transporte de la película, dispuestas una detrás de la otra en la dirección de la luz, sirviendo una de las partes de marco como tope de aplicación para los bordes de la película y con su superficie, vuelta hacia la fuente de luz, define el plano de la ventanilla de imagen, determinante para la nitidez de la imagen y porque la otra parte de marco presenta un saliente, que sobresale en la dirección hacia el plano de aplicación de la primera parte de marco.
